Key figures in a phone-jamming scheme designed to keep New Hampshire Democrats from voting in 2002 had regular contact with the White House and Republican Party as the plan was unfolding, phone records introduced in criminal court show.

The records show that Bush campaign operative James Tobin, who recently was convicted in the case, made two dozen calls to the White House within a three-day period around Election Day 2002 -- as the phone jamming operation was finalized, carried out and then abruptly shut down.
...
Democrats plan to ask a federal judge Tuesday to order GOP and White House officials to answer questions about the phone jamming in a civil lawsuit alleging voter fraud.
...
A Democratic analysis of phone records introduced at Tobin's criminal trial show he made 115 outgoing calls -- mostly to the same number in the White House political affairs office -- between Sept. 17 and Nov. 22, 2002. Two dozen of the calls were made from 9:28 a.m. the day before the election through 2:17 a.m. the night after the voting.

There also were other calls between Republican officials during the period that the scheme was hatched and canceled.
...
Virtually all the calls to the White House went to the same number, which currently rings inside the political affairs office. In 2002, White House political affairs was led by now-RNC chairman Ken Mehlman. The White House declined to say which staffer was assigned that phone number in 2002.
...
Democratic National Committee spokesman Damien LaVera said Monday: "With every development in this case, there are new questions about the extent to which key national Republicans had knowledge of or were involved in a criminal scheme to keep New Hampshire voters from getting to the polls. The American people have a right to know whether the White House political director, who today sits as chairman of the national Republican Party, had any hand in it."

update:
To clarify, it is generally accepted that a sitting president may not be subject to criminal prosecution. But, as those who recall the Paula Jones case against President Clinton will know, a sitting president is subject to civil litigation. And RICO can be applied in civil cases.
